Banks or levees are very important flood control structures and a failure may be catastrophic to surrounding communities. To avoid such disasters, so-called superlevees have recently been constructed in Japan and other countries. The width of a superlevee is about 30 times its height. Buildings and parks are often on the tops of superlevees because they are wide and strong enough to support such constructions (Figure 1).

This article describes a 3D seismic survey of a superlevee along the Tone River, Ibaraghi prefecture, northeastern Tokyo. We employed a 3D shear-wave survey because target features are small and simple 2D reflection profiles might miss the target.
